INSULA'IOR ASSEMBLAGE FOR ELECTRIC CONSTRUCTION.-

Specification of Letters Patent.

Patented Feb. 26, 1918.

Application filed August 23, 1917. Serial No. 187,832

city and county of San Francisco and State, of California, have inventedcertain new and useful Improvements in Insulator Assemblage for ElectricConstruction, of which the following is a specification.

My inventlon relates, in general, to electric-construction, and, inparticular, to the assemblage of insulators in various devices andstructures, such for example as CllSCOh- 'necting switches, main-lineswitches'both inside and outside construction, bus-bar construct on,lnsulation for lines on pole or novel means, which, as will be shown,may properl be termed universal hardware, for

detacha ly connecting-the insulators either singly, or in units ofplural members 'to various structural elements, and for detachablyconnecting a plurality ofv insulators into units of any requiredvoltage.

- These means comprise a novel insulator bell and-a novel insulator pineach adapted for ready and universal detachable rigid connection to eachother and to whatever structural element to which they are to be aplied, all as I shall now fully describeby.

re erence to the accompanying drawings, in which- Figure 1 is anelevation of the insulator pin connectedby its base flange to the cap orhead-of the insulator bell, which latter is in's'ec'tion on theline 11,of Fi 3.

of one disk is cemented the pin 1, while the 'unded by means ofthecumferentially roughened or corrugated, as

shown at 2, to hold the cement by which it is united to an insulatordisk. The foot of the pin is formed with aflange base 3, through thewings of which are made, holes 6' 4 for bolts, an d said base is alsoformed with V.-tongu'es 5 traversing the holes. 6 is the instilatorbell, with an integral head or cap- 7. The interior of the bell iscircumferentially roughened or corrugated as shown at 8, to hold thecement by which it is united to the shank of an insulator disk. -Theupper surface of the cap 7 of the bell is formed with bosses 9 throughwhich are bolt holes 10, and across which are formed V-grooves 11. Theupper surface of the cap is alsoformed with V-grooved lugs 12, as shownin Figs. 3 and 4:, for a purpose tolbe presently described. The pin 1and the bell 6 are detachably connected, as shown in Fig. 1, by thebolts 13,.through the holes {1 and 10 of the base-- flange of the pinand the head of the bell,

5 of the pin base fit the V- grooves 11 of the bell head, and resistshearing or By referring now to' Fig. 5, it will be are assembled thisfigure,14 are the usual insulator disks. Into the body twisting strains.

shank 15' of the same disk is cemented in the bell 6 next adjacent.

-By removing the bolts 13, thedisks'rnay' be readily separated, or theymay be. compounded to any voltage required. Fresh sks may be added toreplace injured or defective ones,

. In Figs. 6' and 7 I show a bearing base 16 which-is formed. with holes17 and V-grooves 18', adapted for the connection of an insulator pinsuch as 1, and by consequence, ofany assemblage of insulators of whichsaid pin forms a part.

In Fig. 8 I show a shaft 19-which may represent the rotatable memberofa. disconnecting switch. This shaft-has end flanges 20 formed with holes21 and V-grooves 22,

adapting it to receive an insulator pin such as 1, and its assemblage,of disks. It will now be seen that the essential elements, namely thepin 1', and the bell 6, are.

universal, and may be used in a practically structures. They yieldadvanvariety of tages, such as the replacement of disks in case ofinjury to any one or more of the disks, without loss of the entire unit;they reduce the assemblage to a minimum num ber' of parts areinterchangeable, and give a a standard or any'combination; they giveopportunity for repairs, due to breakage from-any cause,such as line sures, atmospheric changes, vandalism, or de ects in material which show upin service; they make a rigid unit, which onthis account enables it tobe supported fronra base, either vertically or horizontally 'or at anyangle, as well as being suspended; they provide for the ready andeconomical increase and decrease 4. ofline v.oltages,.and finally, theygive opporsulator pin having a" base flange; and an .lator bell to thehead i o which having a base flange; a memberto'which the.
